WHEEL-RIM.

ap u ation filed March a, 1917, Sen.

. To all whom-itmay concern:

Be it known that I, FRANK LEE DARLING, residing'at Long Beach,'in the county of Los singeles and State of California, have invented a new and Improved Wheel-Rim, of

which the following is a specification.

y invention relates to certain new and useful improvements in wheel rims designed for the quick attachment and removal of pneumatic tires from Wheels and the invention especially has for its object to provide a convenient and effective construction of rim that may be manufactured at a mmnnum expense and is of such design and construction that the tire can be or replaced on the rim with minimum effort with rivet studs that project through aperand withoutthe necessity of removing bolts or nuts. 1

In my present construction, the felly band section of the rim is provided with the ringlike portion at one side which side. of the felly, this portion being provided tures in the ring-like portions and are held from displacement by engaging the felly, the studs projecting through apertures in the opposing rim member and having headed shanks adapted to engage in key-hole slots in a locking ring, the keyhole slots of which are open to the periphery to prevent clog ging by dirt and'foreign substances.

The invention also resides in those novel details of construction, combination and arrangement of parts all of which will be first fully described, then be specifically pointed outin the appended claims, and illustrated in the accompanying drawing, in which:

- Figure 1 is aside elevation of a wheel with theinvention applied.

Fig. 2 is a detail cross section of the same. Fig. 3 is a view similar to Fig. 2 showing the rim members separated and the locking ring also separated.

,46 section showing the position, I

' In the'drawing, 1 designates the felly of Fig. 4 is a detail perspective'view and. part the wheel on'which the rim is held in any well-known manner. The rim which .consti tutes mypresent invention comprises a main member 4 adapted to be fitted nto the felly 3 and at one side the member 4 has a tire engaging flange, and at the other side it has a depending ring-like member which engages the side oi the feilv and is designed g qliegin ciess centadt with the Same. 5 in Specification of Letters Patent.

dicates the other rim member which is equipped to engage the tire and also has an annular ring-like portion to lie against the ring-like member 40 of the rim member 4! 20 designates studs which are passed.

through the apertures 41 in the ring-like member 40 from the felly side and are rivet headed as at 21 to be-countersunk into the apertures 41 and lie snugly against the felly 3 when the ring-like member 40 is lying against the same. The studs 20 have shanks leave heads, the diameter of the heads and the diameter of the shanks of the studs being approximately the same so that the rim member 5 can be easily fitte, over onto the studs in snug engagement with the same.

1 designates a locking ring which is provided with key-hole slots 10 to engage in the necks 24 of the studs, the key-hole slots 10 being opened outwardly toward the periphery of the ring, from dirt and foreign matter in removin the ring-1 for the purpose of demounting the tire.

7 is a latch that is pivoted to the locking ring, and is designed to be brought up to engage an adjacent stud 20 to prevent rotary motion of the locking ringl when the tire is deflated, it being understood that when air pressure is in the tire, ring 1 has retaining frictional engagement with the rim member 5, so that danger of rotation of the ring 1 to tend to unlock it or release it is avoided, the latch 7 being in the nature of a spring snap.

It will be noticed that by inserting the studs 20 from the felly side through the ring member 40, they are held in place without the necessity of fastening them to the memher 40 so that should the studs become damaged in any way, they can be easily removed. and new ones substituted by removing the rim member 4 from the felly.

I have shown no means for fastening the rim member 4: on the telly as any desired means for that purpose may be employed and I do not in this application lay any claim to any particular means for securing the 105 felly of the 7 Wheel will depend upon whether or not it is rim to the felly of the whesi. as the means so as to be readily freed same in the locking and unlocking directions and to facilitate this operation, the ears may have Wrench receiving members 15*, if desired.

In 'order to remove a tire, the latch 7 is moved to the position indicated by the dotted line as in Fig. l, and the locking ring in turn, in. the direction of the arrow y. Any dirt that might have accumulated in the open hole slots will be automatically ejected and thus not interfere with the ready release of the locking ring.

After the locking ring has been removed, the rim member 5 may be also removed and the tire taken from the rim.

To replace the tire the foregoing operations are reversed.

. From the foregoing description, taken in connectlon with the accompanying drawing, it is thought the'complete construction;

operation and advantages of my invention will be readily understood by those skilled in the art.

What I claim is:

1.' As a new article, a rim comprising a. main member having an annular portion to fit on the periphery of the Wheel, one side of said annular portion terminating in a tire engaging flange the other side being provided with an inwardly extended ring member adapted to lie against the side of va wheel folly, studs carried by said ringlike member, a second rim member of ringlike form having a tire engaging flange and apertured to fit on said studs and lie in contact with saidring-like member of said first rim member, and a locking ring cooperating With said studs to hold said rirn members together, said locking ring having open key-hole slots opening toward the periphery of the locking ring and means whereby said locking ring may be turned to lock and unlock the same.

2. A rim comprising a main member having a tire engaging flange at one edge and adapted to fit on the periphery of a wheel, said main member having a ring-like portion at the other edge adapted to project inwardly and lie against the side of a Wheel fell studs carried by said ring-like member and having rivet-heads counter-sunk into the same from the telly side of the ring whereby the said studs will be held in place when said ring-like member is lying against the telly, said studs having constrictions to provide heads, the diameter of the heads and the diameter of the stud body being sub stantially the same a second rim member having apertures to snugly fit on said studs and adapted to lie against said ring-like portion of said first rim member and having an engaging flange portion, and a locking ring having open key-hole slots to cooperate with said studs, the openings of said slots extending to the periphery of the locking ring whereby said slots are selfclearing, and means for turning said looking ring to engage or release the same and a latch device for holding said locking ring against unlocking displacement.

FRANK LE DARLING.
